Decouplable focal distance controller and indicator
11703740 · 2023-07-18 ·

When filming a scene, the focal distance of the video camera is often controlled remotely, and can be switched between manual and autofocus modes. To overcome sudden movements in the lens upon reverting to manual mode, and to avoid disrupting a user's grip on the manual control during autofocus, the traditional distance ring indicator is split into separate controller and indicator components. The controller permits manual input, while the indicator tracks the desired distance. In manual mode, the controller and indicator move in unison. In autofocus mode, the indicator tracks a rangefinder input but the controller is not moved. In a hybrid mode, the controller offsets the rangefinder input. In all cases, the position of the lens moves with the indicator.

Under-display camera and sensor control

An under-display camera is positioned underneath a display of a mobile device. The under-display camera captures an image using light passing through a portion of the display. The mobile device displays a display image on the display, the display image based on the image. The mobile device displays an indicator overlaid over the display image on an indicator area of the display that overlaps with the portion of the display. The indicator may identify the position of the camera. The mobile device can compensate for occlusion of the camera by continuing to display a previous display image if a more recently captured image includes an occlusion. The mobile device can give users alternate ways to select areas of the display image to avoid camera occlusion, for instance using hardware buttons and/or touchscreen interface elements.

In a focusing position detection method, a plurality of object images are acquired by imaging an imaging object by an imager while changing a focal position in M stages along an optical axis. A saturation consecutive region is acquired. The saturation consecutive region is included in all N (where N is a natural number equal to or more than three and equal to and less M) object images acquired while successively changing the focal position in N stages along the optical axis. A focusing degree decrease as the focal position approaches focusing position in the saturation consecutive region. Based on this property, the focusing position is detected.
